HAMMER.

Application lfilcd May 17,

This invention relates to hammers having removable plugs in their facesto adapt them to be used for different purposes; .and

it consists in the novel construction and com-- abutment washer removed. Fig. 4: is a section through the raw-hide plug showing a modification. Fig. 5 is asection through a metal plug before. being inserted 1n the socket, and also showing a modification. Fig. 6 is a .sectionthrough a plug socket, taken on the line 66 in Fig. 1, and showing the metal abutment washer in place.

The hammer is provided with .any approved handle, and preferably a wooden handle 10 has one end portion secured in a hole 12 in the hammer head 14. The hammer head preferably has a similar socket or enlargement 15 at each end, but it may have only one of these sockets, and the other end may be any approved form of strlkmg face or end. When two sockets 15 are provided, one of them is preferably provided with a raw-hide plug 16, and the other with a metal plug 17. Each plug is removable and renewable.

The non-metallic plug 16 may be formed of fiber, raw-hide, or other similar materlal. The metal plug 17 may be formed of copper, brass, aluminum, steel, or other simllar material.

Each socket 15 is cylindrical, and is of the same diameter at each end. Each socket is provided with ejector slots 18 in its sides. The inner ends of these slots extend below the bottom 19 of the socket, and form passages 18 in the bottom, which passages are arranged crosswise of each other. The outer ends of the slots 18 may extend to the outer ends of the socket if desired, but they preferably are formed as shown, so that the metal is not cut away at the outer end of the socket.

The sockets are larger in external diameter than the width of the head between them, and form shoulders 31 as shown in Fig. 2, and the head is provided with a circular recess 20 on each side. When the head is 1927 Serial No. 192,034.

formed in this Way it is'relatively light,-.and well balanced, and is very strong at the sides of the hole in. which the handle issecured. The bottoms of the recesses 20 form convenient places for advertising labels or mono.- grams. a

The metalplug 17 has a dished inner end 22, and when the plug is driven into its sockct the lip 23 at its periphery is expanded into a'circumferential groove-24c in'the .bottom of the-socket. In the modification shown in Fig. 5 theimetalplug 17 has a hemispherical striking face 25, and it has a shoulder 28 which bears on the end of the socket, and :its lip 23 shown unexpanded and ready'for insertion in the socket. ,The socket 15 for a raw-hide plug may also have. a circumferential groove'24, if desired, to enable a metal plug to be substituted for a raw-hide plug. When used only for raw-hide the groove 24 can be left out, as raw-hide cannot be expanded into a circumferential groove like metal. I

VVhen the socket is formed to receive a raw-hide plug, recesses 26 are formed in the bottom of the socket, coaxial with the socket, and at the points of intersection of the ejector slots 18. A circular washer or abutment plate 27 is fitted into these recesses to form an abutment for the end of the central part of the plug, so as to prevent its inner end from being hammered into the passages 20. In order to secure the nonmetallic plug in its socket, two holes 30 are formed in the bottom of the socket diagonally of its axis. These holes 80 extend between the bottom of the socket and the PATENT OFFICE.

opposite points of the hammer head, so that they pull the plug tightly against the abutment plate 27. These screws pass through the said holes and through thearcuate spaces formed between the periphery ofthe abut.- ment plate and the side wall of the socket 15. These holes 30 maybe used as ejector holes for the plug when the screws are removed. Any suitable drift is used which can be inserted in the ejector slots or holes. The

socket for the metal plug preferably has these holes 30, to enable it to have a rawhide plug substituted for the metal plug, if desired.

In themodification of the raw-hide plug 16 shown in Fig. 4,. the plug is provided With a recess 3 1 in its end, and the abutment Washer 27 is sunk into this recess. thus sunk into a recess, the recesses 26 are not required, but the plug and the bottom of the socket may each have Washers fitted into them, the precise arrangement being immaterial so long as a sufficient abutment is provided for the raw-hide plug.

When a hammer head 1s provided wlth re-' movable and interchangeable plugsin this manner it is adapted to a great Variety of uses, and the plugsare not liable to become accidentally detached and lost.

What I claim is: 1. A hammer head provided with a socket having ejector slots in its side wall and bottom and having also holes for fastening in the bottom of the socket leaving'spaces between the abutment pl ate and the side Wall When of the socket, a non-metallic: plug inserted in the socket, and fastening screws passing 30 through the said holes and spaces and securing the plug tightly against the abutment plate- 2. A hammer head as set forth in claim 1, and having a recess formed in the bottom of 35 the socket for the reception of the said abutment plate.

3. A hammer head as set forth in claim 1, and having 'a recess formed in the bottom of the socket for the reception of the saidabut- 40 ment plate,.the said plug having also a recess in its inner end, and an abutment plate inserted in the recess in the plug and arranged to bear against the abutment plate in the bottom of the socket.

4; A hammer head as set forth in claim 1, thesaid socket forming an externally pr0- jecting shoulder on each side of the handle" portion of the head, and the said screws having heads which bear onthe shoulders 50 Without projecting laterally beyond-the: periphery of the socket.

In testimony whereof I have afiixed my=' signature.
